Hah, didn't think about Java 8 default methods in interfaces. Of course,
you're right.
Your above last set of changes looks excellent, but in GrokParser the
methods configurationUpdate() and init() have to become synchronized methods.
Then I think the code as written allows the configurationUpdated flag to not
need further locking, altho different ordering of things might require
synchronized get/set/check methods.
